GCC 4.8 and its prerequisites have been removed by 04dce680, 41d4583a
and e4221734; as a result, 4.8-based version of gcc-oracle became
unbuildable (no valid versions for the prerequisites).
Update the samples to use 4.9.4; which however fails to build on a modern
host GCC. Build fix backported to gcc-4.9 and gcc-5 versions.
Fix binutils-oracle build with host GCC11.
